Short Machine Tap DIN 352 Form B HSSE - M 8 x 1.25

• Create metric ISO internal threads in steel and comparable alloys, depending on the workpiece condition and cutting fluid.
• Use when you want predictable thread geometry for assembly without additional forming steps.
• Often selected for through holes where chips can move forward through the bore, depending on the setup.
• Applied in repair and production environments where you need repeatable thread quality for assembly.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Align the tool to the hole axis, use appropriate lubrication, and clean the thread after tapping to avoid assembly issues.

• Short pattern supports efficient handling in holders and collets
• HSSE material supports repeatable edge strength
• Form designation supports controlled lead geometry
• Suitable for general purpose internal threading
• Supports consistent assembly fit when preparation is correct

• Not suitable for very hard or highly abrasive materials, depending on execution
• Not intended for high performance tapping without rigid guidance and controlled coolant

1. Check the drawing and confirm thread specification.
2. Prepare the predrilled hole and remove entry burrs.
3. Fix the component so the hole axis stays stable.
4. Mount the tap in a stable holder and keep alignment square.
5. Use a suitable cutting fluid for the material.
6. Start tapping with steady feed and consistent rotation.
7. Pause if chips build up and clean the cutting area.
8. Back the tool out and inspect the thread flanks.

A short machine tap supports compact setups and stable tool guidance in many holders. It is practical when you want efficient tool handling and repeatable internal threads.

Form B is often selected when chips can move forward through the hole. Spiral flute executions are commonly selected when you want chips transported back toward the entry, depending on hole type and process strategy.

Yes, depending on your holder and setup you can drive the tool by hand or with a machine. Focus on alignment, lubrication, and controlled torque to protect the cutting edges.

Yes, depending on your holder and setup you can drive the tool by hand or with a machine. Focus on alignment, lubrication, and controlled torque to protect the cutting edges.

Typical signs are rising torque, rough thread flanks, and inconsistent fit with the mating part. Replace the tap if the cutting edges look rounded or chipped.
